If you use fake_module() to mock a module that already exists in memory -- one you've loaded elsewhere perhaps, but do not pass any subroutines to mock, this method will throw an exception. This is because if you call the constructor later on, you probably won't get a mock object back and you'll be confused.

When putting a smiley right before a closing parenthesis, do you:

Use two parentheses: (Like this: :) )
Use one parenthesis: (Like this: :)
Reverse direction of the smiley: (Like this: (: )
Use angle/square brackets instead of parentheses
Use C-style commenting to set the smiley off from the closing parenthesis
Make the smiley a dunce: (:>
I disapprove of emoticons
